Solve equation 1/4=x^-1/2
Alex

Answer:

A. {16}

Step-by-step explanation:

1/4 = x^-1/2

We have the exponent rule a^-1 = 1/a^1

Applying the rule, we get

1/4 = 1/x^1/2

x^1/2 = √x

1/4 = 1/√x

Now let's cross multiplying, we get

√x  = 4

Taking square on both sides, we get

x = 16

The answer: A. {16}

Hope this will helpful.

Thank you.

marta [7]
S= number of small boxes
l= number of large boxes

equation 1:  s+l=120
equation 2:  15s+45l=3300

solve by elimination, multiply equation 1 by -15.

-15(s+l=120) =  -15s-15l=-1800  add to equation 2.

-15s+15s-15l+45l=-1800+3300  = 30l=1500

30l=1500 , l=50

s+l=120, s+50=120 --> s=70
